Wasabi is OK. But we prefer Zen Sushi. It's about two miles north of downtown on Merrimon Avenue (US Rte 25). It'll be on the left as you go north and it's in a strip mall, but don't let the location put you off. They have excellent lunchtime sushi specials...

Wasabi is good, as is Zen Sushi, I've heard good things about Green Tea but not been there...There are two new places opening up on Biltmore Ave, one is by the same family who has Wasabi, Ichiban and CF Chans and the other is a stand alone, should be interesting :)
